Abstract: For the multi-demand environment of old-for-new purchase,old-for-remanufacturing purchase,direct purchase of new products and remanufactured ones,the market formation conditions and demand functions were analyzed,and a two-stage differential pricing model for the monopoly manufacturer to recycle and remanufacture was constructed.The influence of replacement recycling prices,government replacement-subsidy,used products' residual value and remanufacturing capabilities on product pricing,production decisions and profitability was explored.The research showed that the market sales of old-for-remanufacturing would continue to increase with the increase of replacement and recycling prices,but the market sales of old-for-new would remain stable or shrinking according to the changes in the total amount of remanufactured products;when the total amount of remanufactured products was less than the amount of recycling of used products,the increase of government replacement-subsidy would result in a decline in the total profit of the manufacturer,and only when the subsidy amount exceeded a certain threshold,the total profit would rise again;the effect of residual value of used products on the product sales price and the sales quantity was just the opposite of the replacement recycling price,but both of them would basically lead to the decrease of the total profit of the manufacturer.

Key words: old-for-remanufacturing, old-for-new, product pricing, production decision, remanufacturing

摘要： 针对市场上存在“以旧换新”式购买、“以旧换再”式购买、直接购买新产品和再制造产品的多元需求环境,分析了市场形成条件和需求函数,构建了垄断制造商进行回收再制造的两阶段差异定价模型,探讨了置换回收价格、政府“以旧换再”补贴、废旧产品残值和再制造能力对产品定价、生产决策和制造商利润的影响。研究表明:①随着置换回收价格的增加,“以旧换再”的市场销量不断提升,但“以旧换新”的市场销量会依据再制造产品总量的变化,保持稳定或不断萎缩;②当再制造总量小于废旧产品回收数量时,政府补贴的增加,会导致制造商总利润下滑,只有当补贴额度超过某一临界值时,总利润才会回升;③废旧产品残值对产品销售价格和销售数量的作用规律与置换回收价格刚好相反,但两者基本上都会造成制造商总利润的降低。
